If the instruments on-board the Curiosity Rover (which is currently located on the surface of Mars) have any degree of temperature accuracy, then Michigan is within an area of North America that is colder than Mars.

According to a tweet from @MarsWxReport, the Curiosity’s location in Gale Crater (somewhere on the surface of Mars) is warmer than all of Michigan, parts of Wisconsin, and at least the southern parts of Canada.
